I have a friend that has a claimed to be '42 special deluxe for sale (1500.00) that still has the beauty rings and hub caps and no rust through(minimal surface) and motors spins. what are the identifing marks say its a '42 and not a '46 since the body didnt change that I should look for? some say knuckle grips on the steering wheel and others say a "spoiler" under the front bumper which it does not have. I figuered I would ask the experts, Any help?[S
